    Levo Gen 3 Specialized Turbo Levo, S2 or S3?

    Same size as you and I went with the S3 but tried to find an S2. The S2 reach and wheelbase are very close to my 2022 SL medium which feels just right. My S3 just feels too big with too much weight on my hands when seated. I recently lowered the saddle a lot and pushed the seat forward all...

    Levo Gen 3 Charge Limit doesn't work anymore

    Don't bother asking. The answer is that they are working on a fix. Can't be more than a one day job but they are taking forever and so it must be the lowest priority for them. As a former mechanical engineer and also a programmer of CADCAM software for over 10 years I'd personally be so...

    Levo Gen 3 Charge Limit doesn't work anymore

    I had no idea there were two apps and have always only had the Mission Control app which they did recently update with the 80% charging feature. I guessing again, but probably both of them have this issue. I will download the Specialized app anyway so I at least have 10 80% charges. Not sure...

    Levo Gen 3 Charge Limit doesn't work anymore

    So to be clear the app works for SL but the new 80% charge feature has a bug that makes it stop working. Everything else works. I'm not sure but I imagine this 80% charge issue is a problem with app not any specific motor. But I do know it's an issue with my 2021 SL.

    Levo Gen 3 Charge Limit doesn't work anymore

    No they told me yesterday by email that they are still working on it. The app online is dated back in August so it has not been updated yet. Reloading it will probably get it to work for a while I imagine and I might try that too. Sort of like what a reset does, but temporary.

    Levo Gen 3 Charge Limit doesn't work anymore

    Yes they did add it and it typically works for a while. I think mine might have worked for 10 rides at which time it's designed to do ONE 100% charge for battery health and then should go back to 80%...which mine, and many others (maybe all), didn't do. Specialized acknowledges there is a...

    Levo Gen 3 Charge Limit doesn't work anymore

    Looks like the reset isn't a lasting fix and I expect there will be an update someday.

    Levo Gen 3 Charge Limit doesn't work anymore

    This was such a great feature for the 1st 10 charges and now my 2021 expert carbon sl charges to 100%. I'm not going to do the reset since it seems that's necessary every 10 charges. Spec has had plenty of time to fix this simple feature and yet nothing yet. Why the delay??? Just contacted...

    Levo SL Gen 1 Lightest sl levo builds

    OK, guess I'll start. 38 lbs. Expert Carbon, magnesium flats, CF bars, X01 cassette and CF Specialized rims with 29"x2.6" Specialized stock tires, Lyrik ultimate forks and DVO shock but currently running the stock FOX Grip2 and dpx2 shocks so slightly heavier. Hard to go much lighter than...

    Levo SL Gen 1 Official Levo SL Thread

    I would worry about overheating with any external sound insulation. I suspect the straight cut gear design and/or gear materials changed to lower the noise a lot. Adding things like silicone and teflon to the plastic gear can help a lot. And also designing a gear with a much higher AGMA...

    Levo SL Gen 1 The Reason for delay in 2023 Levo SL...(and various other discussions on lightweight bikes......)

    Companies drag their feet for the obvious reason that the product is not finished yet, has issues they are working out and/or might not meet spec. Marketing will always try to push hardest for the earliest release in spite of this depending on how well they understand technical issues. It...

    Levo SL Gen 1 Can hear a dry sort of whistling sound from my Sl motor when back pedaling

    I just noticed this today on my 2021 Sl Expert with about 1500 miles on it. When I backpedal there's a dry sort of whistling sound coming from the motor. I just noticed this while lubing my chain and not pedaling. It's pretty consistent and not really loud but noticeable. I think I would...

    Levo SL Gen 1 The Reason for delay in 2023 Levo SL...(and various other discussions on lightweight bikes......)

    Yeah there's that saying, "don't fix what isn't broken". I now have 1400 trouble free miles and very happy with how my "sewing machine sounding" motor has performed. I really have adapted to the sound and it's really not that offensive. If Specialized should come out with a new quieter one...

    Levo SL Gen 1 The Reason for delay in 2023 Levo SL...(and various other discussions on lightweight bikes......)

    It's all related and rpms of course will make any gear set louder but especially straight cut gears. About 20 years ago I worked on noisy gears used in a medical device. They were silicone and teflon impregnated acetal (delrin) gears that initially were designed with only a 4-6 agma rating...

    Levo SL Gen 1 The Reason for delay in 2023 Levo SL...(and various other discussions on lightweight bikes......)

    Yeah I saw those and did try them but my helmet strap was about an inch from the side of my face rendering it ineffective. Growing your hair long on the sides works too. But I found the first ones I had, Rexton BiCore sat too high and these Philips are more in back and the noise reduction...

    Levo SL Gen 1 The Reason for delay in 2023 Levo SL...(and various other discussions on lightweight bikes......)

    Hmm, have to pay better attention. My E8000 was noisy too but different and not too offensive. And yes I have trouble hearing other riders but it's my hearing and not the bike so much. I now have hearing aids, lol. But there are some issues with wind noise and my 2nd set are made by Philips...

    Levo SL Gen 1 The Reason for delay in 2023 Levo SL...(and various other discussions on lightweight bikes......)

    By "lumps" do you mean sound or resistance? Mostly you really get used to the noise like tinnitus I guess. But it is a factor for many. For instance I probably would not buy a bike with the new Bosch or Shimano motor because of that clunking sound they can make (varies from frame to frame it...

    Levo SL Gen 1 The Reason for delay in 2023 Levo SL...(and various other discussions on lightweight bikes......)

    Not sure the noise is from the bearings. Straight cut gears are always going to be noisier but very efficient. Could be the agma quality of the plastic gear that contributes but I don't know where the design is on this and doubt that Specialized didn't know this motor was a bit noisy and they...

    Levo SL Gen 1 The Reason for delay in 2023 Levo SL...(and various other discussions on lightweight bikes......)

    So on point. The current SL has plenty of power, at least for this 73 yr old. I really can't keep up with the 85 nM 55+lb bikes now but ride with mostly analog bike owners and it's the perfect bike to keep up with the younger riders. Moderate geometry might be the only criticism I might have...

    Retired mechanical engineer wishing he was young again, for so many reasons, lol.
